Technology Unit

: Electrolysis Unit
: Dow Chloralkali
Short Name: Electrolyzer
Description: Direct electric current is applied to the nearly saturated, purified and heated Brine. The Anode is separated from the Cathode by a Permeable Asbestos-Based Diaphragm to prevent the Caustic Soda from reacting with the Chlorine. The Chlorine produced at the Anode and the Saturated Brine flows through the Diaphragm to the Cathode Chamber. The Hydrogen produced in the Cathode Chamber is removed, The Caustic Brine produced at the Cathode is separated from Salt and sent to the Evaporator.
